The correlation between different types, fetal malformation and pregnancy outcomes were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among the 88 fetuses, there were 39 cases (44.32%) of type A1, 40 cases (45.45%) of type A2, 8 cases (9.09%) of type A3, and 1 case of type A4 (1.14%). There were 16 cases (18.18%) with isolated CAT, 48 cases (54.55%) with complex intra\u2010cardiac structural abnormalities, and 24 cases (27.27%) with intra\u2010cardiac and extra\u2010cardiac structural abnormalities. In extra\u2010cardiac structural malformations, 14 cases were associated with 1 other system abnormality, 4 cases with 2 other system abnormalities, 3 cases with 3 other system abnormalities, while 3 cases were combined with 4 other system abnormalities, among which the facial and physical abnormalities had the highest incidence (39.13%). The STIC images were completely displayed in all 88 cases. There was a statistical difference between isolated CAT and CAT combined with other abnormalities in fetal pregnancy outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Prenatal ultrasound had a high clinical application value in CAT classification. Pregnancy outcomes were highly correlated with the classification and associated intra\u2010cardiac and extra\u2010cardiac structural malformations. The early evaluation of fetal prognosis before birth has important value for clinical intervention.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jcu.23518","type":"journal-article","created":{"date-parts":[[2023,7,10]],"date-time":"2023-07-10T11:44:03Z","timestamp":1688989443000},"page":"1182-1187","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Clinical
